摘　　要：In this paper experiments with two upper plenum core structures, the upper plenum corestructure of Qinshan Nuclear Power Station No.1 Project and its improved core structure,respectively, are carried out in a 1/4 scale transparent model of the PWR upper plenum ofQinshan Nuclear Power Station No.1 Project. Water is chosen as the fluid. The experimentalresults are compared and analyzed carefully. The complex flow velocity distribution is ob-tained in the experiment with each core structure. The conclusion that the improved upperplenum core structure can reduce the hydraulic load on the drop of cootrol rods is drawn.In this paper experiments with two upper plenum core structures, the upper plenum corestructure of Qinshan Nuclear Power Station No.1 Project and its improved core structure,respectively, are carried out in a 1/4 scale transparent model of the PWR upper plenum ofQinshan Nuclear Power Station No.1 Project.
